The development of new materials leading to more efficient and cost-effective carbon capture processes has attracted increased attention due to elevated CO2 levels in the environment. Ionic liquids (ILs) are one promising class of building blocks for potential CO2 absorbents due to their negligible vapor pressure, non-flammability, and high thermal stability. Additionally, ILs have tunable properties such as viscosity, CO2 solubility, and functionalization of the cations or anions, thereby offering a wide range of structures with desirable characteristics for carbon capture. We have synthesized a variety of amidine- and imidazole-based ILs and explored their physical and chemical properties, including their potential use in supported ionic liquid membranes (SILMs) for CO2/N2 separations.
